Is it possible for aiohttp to bind to multiple ports especially for websocket?

[Zhaoxun]

I know for different incoming connections I can route them to different paths in aiohttp, like django does.

But I have a cluster of internal servers and want their connections to come from a totally port different than the one a client visits for security. Then since I know exactly where other servers are, I can easily set up firewall rules to restrict that specific port to host connections from a specific IP address (or specific subnet) to avoid a malicious client mocking a server to connect to this aiohttp server program, which only requires knowing the correct path.

So is it possible for a "web.WebSocketResponse()" to bind to another port? Or only one tcp can be used for one aiohttp python program?
